Network Address Translation
Network Address Translation (NAT) allows multiple users to access outside resources such
as the Internet simultaneously with one IP address/one Internet access account. Many
application layer gateways (ALG) are supported such as web browser, ICQ, FTP, Telnet,
E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.
Firewall
NAT technology supports simple firewalls and provides options for blocking access from
the Internet, like Telnet, FTP, TFTP, WEB, SNMP and IGMP.
Domain Name System Relay
Domain Name System (DNS) relay provides an easy way to map a domain name with a
user-friendly name such as www.google.com with an IP address. When a local machine
sets its DNS server to the router's IP address, every DNS conversion request packet from
the PC to this router is forwarded to the real DNS on the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. To use the service, you must first apply for
an account from a DDNS service such as http://www.dyndns.org/.
PPP over Ethernet (PPPoE)
The BiPAC 7300(G) RA provides an embedded PPPoE client function to establish a
connection. You get greater access speed without changing the operation concept, while
sharing the same ISP account and paying for one access account. No PPPoE client
software is required for the local computer. Automatic Reconnect and Disconnect Timeout
(Idle Timer) functions are also provided.
Quality of Service (QoS)
QoS gives you full control over which types of outgoing data traffic should be given priority
by the router, ensuring important data like gaming packets, customer information, or
management information move through the router ay lightning speed, even under heavy
load. The QoS features are configurable by Internal IP address, External IP address,
protocol, and port. You can throttle the speed at which different types of outgoing data pass
through the router, to ensure P2P users don't saturate upload bandwidth, or office browsing
doesn't bring client web serving to a halt. In addition, or alternatively, you can simply
